Bravado

------------------
- Introduce the HTTPFuture.response API as well as support for returning a fallback result. - PR 365, 366, 367, 368

*NOTE:* Most of this API is not documented yet and is considered experimental; we're working on stabilizing it
and providing developer documentation.

------------------
- Fix msgpack import issue - PR 341. Thanks Jesse Myers for your contribution!

------------------
- The timeout exception for the requests client should inherit from ``requests.exceptions.ReadTimeout`` instead of ``requests.exceptions.Timeout`` - PR 337

------------------
- Support msgpack as wire format for response data - PR 323, 328, 330, 331
- Allow client to access resources for tags which are not valid Python identifier names, by adding the ``SwaggerClient.get_resource`` method.
For example, ``client.get_resource('My Pets').list_pets()`` - PR 320. Thanks Craig Blaszczyk for your contribution!
- Unify timeout exception classes. You can now simply catch ``bravado.exception.BravadoTimeoutError`` (or ``builtins.TimeoutError`` if you're using Python 3.3+) - PR 321

------------------
- Allow users to pass the tcp_nodelay request parameter to FidoClient requests - PR 319

------------------
- Make sure HTTP header names and values are unicode strings when using the fido HTTP client.
NOTE: this is a potentially backwards incompatible change if you're using the fido HTTP client and
are working with response headers. It's also highly advised to not upgrade to bravado-core 4.8.0+
if you're using fido unless you're also upgrading to a bravado version that contains this change.
